FHA-C Mini

FHA-C Mini integrates a synchronous servo motor, strain-wave gear and output bearing into a hollow-shaft actuator for compact precision mechanisms. The central opening provides a route for cables, shafts or services through a robot joint. Its cross-roller bearing carries radial, axial and tilting loads, which can let a machine designer attach the driven structure directly without installing another output bearing.

The family comprises sizes 8C, 11C and 14C with reduction ratios of 30, 50 or 100. Depending on size and ratio, published maximum torque extends from 1.8 to 28 newton-metres and maximum output speed from 60 to 200 revolutions per minute. Incremental RS-422 and multi-turn absolute EnDat feedback options suit different controls. Selection must account for duty cycle, bearing loads, acceleration, thermal limits and required positioning performance.
